Screen



No v. l7, 1931. N 1,832,776

SCREEN Filed March 16, 1929 gwuentoo Patented Nov. 17, 1931 UNITEDSTATES RA orrica This invention relates to new and useful improvementsin screens and more especially to a device of this kind used for thepurpose of screening the water that flows from the cooling jacket of theengine of an automobile or other internal combustion into the radiator.I

One object of my invention is to provlde a screen of the characterspecified that is visible at all times when in position and may bereadily removed and cleaned when required to promote the free passage orc1rcu lation of the water therethrough.

With the foregoing and other obgects in view that will appear as thenature 0 my invention is better understood, the sam e con'- sists in thenovel features of construction, combination and arrangement of partsillustrated in the accompan ing drawings and more particularly pointeout in the appended claim. v In the accompanying drawings, which are forillustrative purposes only and are there fore not drawn to scale:

Figure 1 is a side elevation, illustrating the application of myinvention.

Figure 2 is a longitudinal section, taken through the screen and thehose connection, with the parts represented on an enlarged scale.

Figure 3 is a vertical transverse section, taken on line 33 of Figure 2and Figure 4 is a detail side elevation of the screen per se.

Referring to the drawings for a more particular description of myinvention and in which drawings like parts are designated by likereference characters throughout the several views, the numeral 1designates the engine engine of an automobile of any ordinary orapproved construction, 2 the radiator, 3 the outlet tube or nozzleextending from the cooling jacket of the engine, 4 the inlet tubecommunicating with the top of the radiator and 5 the hose connectionbetween the outlet and inlet tubes 3 and 4, respectively.

In carrying out my invention, I make the hose connection in two separatecorresponding longitudinally spaced sections 6 and 7 and provide metaltubes 8 and 9 which are inserted in the inner ends of the hose sec-.

flange 14 which fits between the tions. It'will noted that the innerends of the metaltubes 8 and 9 are provided, with annular collars orflanges 10 and 10 which:

fit against corresponding ends of the hose sections'dand 7 also that theinner ends of the metal tubes 8 and 9 extend somewhat beyond the innerends of the hose sections and support the ends of a hollow cylindricalsleeve 11 of glass or other suitable transparent material.

A cone-shaped screen 12 of wire mesh or other suitable reticulatedmaterial is mount-- 'ed in the transparent sleeve 11 and this screen isprovided at its basewith a circular rim 13 which fits over the innerprojecting end of the metal tube -8 and at the extreme inner edge of therim 13 with an annular collar or flange l0 and the adjacent end of thetransparent sleeve 11, whereby the screen is firmly but removablyclamped in position.

The outer ends of the hose sections 6 and 7 are removably secured tothemetal tubes 3 and 4 by the clamps 15 and 16, or other equivalent means.

The screen 12 will screen the water that flows from the cooling jacketof the engine via the outlet tube 3 into the radiator. This will keepthe radiator free of any dirt or other foreign matter that might causedamage or impairment thereof and will allow a better circulation of theWater, thus increasing the efficiency of the cooling system of theengine generally. The screen is visibleatall times and in the event itshould become choked u and interfere with the free assa e or circu ationof the water theretl iroug 1, may be easily and readily removed andcleaned. Gaskets 17 are arranged between the opposite ends of the hollowtransparent sleeve 11 and the annular collars 10 and 10' at the innerends of the metal tubes 8 and 9 and the pressure on said gaskets is suchas to prevent leakage.

From the foregoing description taken in connection with the drawings, itis thought that the construction, operation and advantages of myinvention Will be readily understood without requiring a more extendedexplanation.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is:

In combination with the cooling jacket of 5 an automobile engine and theradiator, a hose connection composed of two corresponding longitudinallyspaced sections, metal tubes extending into the inner ends of the hosesections, a hollow trans arent sleeve fitting over the inner ends of 510metal tubes a cone shaped screen disposed within the trans arent sleeve,said s eeve provided at its ase with a circular rim which fits over theinner end of the adjacent metal tube, annular 15 collars formed at theouter ends of said metal tubes and gaskets between opposite ends ofzlsaid hollow transparent sleeve and said colars.

In testimony whereof he aifixes his signa- 20 ture.
